Analysis

Acft landed short of threshold following a low release shortly after t/o. release was low due to tow plane's being unable to climb above 200' AGL due to the glider's spoilers being deployed inadvertently during the t/o. the plt stated that he executed a 270 deg turn to return to the threshold instead of making a 90 deg turn to the rwy. Plt was unaware of the spoiler deployment despite the grnd crew's attempts to warn him by radio. The radio volume was turned down.
